To all (whom it may concern: f

Be it known that l, ALBERT GL PAULS i Mumia, a citizen of the UnitedStates, residing at Alameda, in the countyofi'ldlameda:

5 and State of California, have; invented new and usefull-Improvements-in. utomatic Stuiling-BoXes,'-of. which the yfollowing is a"specification, 'Y

This inventionrelates ,to angautomatic 1o. stuffing box and particularlyto means :tor`

insuring perfect lubrication of VAthe shaft lbearings in a deep twellpump. l

. In ,practically every instance where cen'-` trifugal pumps ofi' thedeep well type are' employed, it 1s necessaryduringthe instalV lationto'submerge the pump fa considerable distanceydue to the rise" and fallof the lwater in the well caused by intermittent `operation'-ofthepumpand chang-finv sea"- v sons.- i In a, pump that is submerged, ithas' heretofore been aphys'ical impossibility to keepthe water intheVwell away from the bearing inmediately above theftop runner of the pumpand successive bearings above the same. A stuffing box hasnev'er givensatisfaction. Because of its inaccessibilitv,v

re-packing thereof is prevented, thereby d efeating the purpose forwhich such devices have been designed in the past.

The object of the. present invention is'to provide means for removingany water that` may have accumulated in the shaft tubing"r /rotateswithin a suitable recess of cross section, thus avoiding excess leakageor around the bearings mounted therein;

the moment the pump is'started and .for maintainingA the tubing andbearings'entirely free of water as long as the pump is in: operation,thereby permitting a free How of lubricant to the bearings. Furtherobjects will hereinafrllrrappear. i

The invention consists oflthe parts and the; construction, combinationand arrange- Referring to the drawings in detail, A in dicates ingeneral the well. casing, on the lower end of which is supported a deepwell pump of the centrifugal type, said' pum comprising a casing 2 inwhich is mounte one or more impellers as shown-rat 3 and 4.
